BINDING ATTACHMENT FOR SEWING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 293,022, dated February 1884.

Application filed April :28, 1883. ()lodvl.)

subject of the Emperor of Germany, and a resident of New Orleans, in the parish of Orleans. and State of Louisiana, have invented a new and useful Improvement in Binding Attachments for Sewing-Machines, of which the following is a specification.

This invention relates to that class of binders which are used as attachments to sewing machines to guide a binding to be sewed upon the edge of a garment; and it consists in the construction and combination of parts forming the sewing-machine binder hereinafter described and claimed, reference being had to the accompanying drawings, in which- Figure 1 is a top view of my binder, and Fig. 2 is a bottom view of the same. Fig. 3 is a top view of the adjustable guide for the upper edge of the binding, and Fig. 4 is an edgeview of the same. Fig. 5 is a section, part in elevation, at line aa; of Fig. 8. Fig. 6 is a front view of the binder closed, and Fig. T a similar view of the same open to receive the goods to be bound. Fig. 8 is a sec tion, part in elevation, at line z z of Fig. 1. Fig. 9. is a top view of the guide for the lower edge of the binding. Fig. 10 is a top view of a portion of the lower plate near its discharge end, and Fig. 11 is an under side view of the adjacent face of a portion of the upper plate.

Fig. 12 is asection at 3 y, Fig. 11. Fig. 13 is a rear view of the discharge end of the upper plate, and Fig. 14 is a side elevation of a sliding device for opening the plates.

A is the body or lower plate of the loinder adapted to rest on the sewing-machine plate,

and to be there held by screws at Z Z passing through the tang I of said plate A. A portion, A, Figs. 5 and 6, of plate A is bent back over itself, leaving a passage between for one edge of the binding. This bent edge and the passage made thereby are gradually twisted from a horizontal position at A to a vertical position at A.

B is an upper plate, secured upon plate -A by two screws, 0, Fig. 1, said plate being bent and twisted similarly and oppositely to plate A, mating the same to form one passage therewith for the binding to pass through. The binding is'entered at a, and is kept from being drawn outward through the central space by the curved point (1, extending over it across its line of travel. A binding not wide enough to fill the passage a, will be guided on the binding.

s is a projecting shelf, which, in connection withthe edge 3 and hook q, prevents the guide g from being dislocated.

k and Z represent the two arms of the upper guide. Each of these arms has a downward flange, 7., Fig. 2, and Z, Figs. 4 and 5, 'standing in line with each other, forming a double guideto the upper, edge of the binding.

d, Figs. 1 and 2, is a bent-up portion of plate A, serving as a fixed back guide for the folded edge of the binding. The double guide is Z is a binding-screw, Z, passing through a slot, 17, and one of the plate-securing screws passing through slott", permitting it to be set at different distances from the back guide, (Z, to reeeive bindings of different widths.

edge of thebinding may, if so desired, be guided to lie farther onto the garment than the other edge; yet both, requiring to be set when beginning to work, are bound when set by the same screw, The, guide 7c Z is provided with a handle, 0, and the guide It Z witha similar handle, 0, by means of which handles the two guides may beset. The arm is of the upper guide is provided with a lip, k to extend beneath the upper edge of the binding, to insure its lying out fiat at the instant before it is sewed, and so prevent the edge of the binding from working out from the guide, said lip being just beforethe hole through which the needle plays. The arms Zand Z enter the plates A and B through apertures Z and Z respectively, andengage the edges of said apertures centrally therein by the spring-guide q, hav:

adj ustably secured tothe plate A by means of is Z represent a similar guide,which may be setindependently of the upper guide, so that one or broken off by any sudden backward pull as sliding ways, thus keeping said guides in a fixed relation to said plates and to the binding guided thereby. The said arms thus act as springs to hold plates A B together, and the guiding-edges of said plates are somewhat rigid on that account; but the associate guides I: and k are each free to spring as the thickness of the garment may require, so that they properly guide the binding just before it is sewed, whether the garment be plain or crossseamed.

m and m, Figs. 10 and 11, represent diagonal bars secured upon the inner faces of plates B and A at an angle with the path of the garment, acting like plowshares to crowd the edge of the garment into the binding, and to force that against the back guide, (Z.

a and a represent diagonal serrations on other planes of the same plates, to act in a simi lar manner on the binding to stretch it smoothly onto the garment. The plate B has a downward-inclined edged projection, which passes through opening f in plate A, to raise said plate B by means of a handle, G, adapted to slide av plate, f, Fig. 10. beneath said inclined edge. The sliding handle G is provided with a spring, h", Fig. 2, secured thereto by means of studs g and g, to act against plate A, cansin g sufficient friction tohold handle G wherever it is left. This raising of plate B is to admit the goods between it and plate A. The presscr-foot of the sewing-machine springs down upon guide 7;, pressing it upon the goods.

In operation, the binding is placed behind arm 8. passage a, into which it is entered and worked forward by means of any pointed instrument inserted in the middle space. W'henit projects beyond the serrations a n, the edge of the garment is inserted between plates A B againstpxtensions c and 0* of plates B and A,

which project across the opening between said plates, to prevent the garment from coming in contact with the binding until the two pass simultaneously to be sewed, and both are drawn forward together, the edges of the bi nding being first guided behind the lips 7c" and chine-feed drawing all parts of the work along together.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. The plate A, adapted to be attached to a sewing-machine, substantially as described, in combination with the plate B, secii red at its outer endto plate A, springing its inner end thereon, each plate being folded back nearly upon itself at one edge, each of said folded portions being twisted from a horizontal position at its inner end to a vertical position at its outer end, theoriginal outer edges of the two folded portions being contiguous when l'ol'dedand twisted as described, forming a pas Guide (1 is set to bring it central with I Then the sewing may be done, the ma-' ioaoee sage whose inlet is a vertical plane and whose outlet is two parallel horizontal planes j oiued at one edge, as and for the purpose specified.

2. The plate B, folded and twisted as described, in combination with the plate A, folded and twisted as described, and having the point a lying across the line of the opening between the adjacent edges of said plates.

3. The eombination,with the plate A, having the notches 12 therein, of the guide q 8, having an elastic body attached to said plate, adapted to spring into the aforesaid notches, as shown and described.

4. The plate A, having the notches p and rib s, in combination with the guide q, having the hook q, adapted to hook loosely over the rib s, as shown and described.

5. The plate A, having ahole, f, in it, and the plate B, having the inclined-edged projectionf, adapted to pass through said hole f, in

combination with the slide G, provided with a plate, f adapted to slide between plate A and projection f to raise the plate B, as shown and described.

6. The combination, with the plate A, having two slots in it, of the slide G, having two studs, 9 g, and the spring 76-, heldby said studs, impinging upon one side of plate 'A to hold slide G in frictional contact with the other side, as described. 1

7. The folded and twisted plate A, having the extension 0', in combination with the folded and twisted plate B, having the extension 0, adj acentto each other, as shown and described.

8. The combination, with the guide Z, having the flexible arm 70, each provided with guiding edges in line with the other, of the guide Z, having the flexible arm is, each provided with guiding-edges in line with the other, substantially as described.
